Preheat oven to 375 degrees and grease baking sheet.
In a large bowl, combine flour, ⅓ cup of sugar, baking soda, baking powder, salt and softened butter. Mix in the buttermilk and egg until dough starts to form, then fold in raisins. If dough is still crumbly, add a splash of buttermilk until it comes together.
Knead dough on a floured surface. Form into a round loaf.
Brush the top of the loaf with ¼ cup of melted butter then sprinkle ½ tablespoon of sugar on top.
Cut an X into the top of the loaf using a sharp knife.
Bake on a baking sheet for 1 hour. Test to see if it is done by inserting a toothpick into the center and checking to see that it comes out clean. If the loaf is too thick, the center might take longer to bake. Simply place some foil over the top of the loaf and continue baking until done.
Remove from pan and allow to cool on a wire rack.
